If you believe that the government, state, federal, or otherwise, has the power to remove child from natural parent, then anything else you claim to believe as an supposed individualistic, non-intrusive government "conservative" is meaningless. If this mother is guilty of aggravated assault, then arrest her and charge her with aggravated assault. If she is convicted, then she should go to prison, and the child goes into the sole custody of the father or next of kin, aka closest living relative. If the mom is found not guilty, then she is not guilty, and she goes home with her daughter. At NO TIME should a child be in the custody of a government agency. Government has not been delegated that authority by the people.
One more session with the bong this evening ought to calm you down again, bud.
So what you're saying is we should wait until a child is permanently injured or dead to do something about an abusive parent? What logic.
